Claims vs reality
Where the brand’s marketing and its own small print don’t agree.
They sayLawnMaster sells the OcuMow 16 as a mower that needs no wire or installation.
In practiceCorrect, but LawnMaster also says it needs a clearly defined lawn edge, such as paving, gravel or a raised edge of 6 cm or more. It won't suit borders, overhanging plants or drop-offs. Source
They sayThe two-battery kit is listed for 300 m².
In practiceThat's two separate 150 m² runs: you swap in the second battery yourself when the first runs flat. Source
Which version do you need?
The one-battery kit covers 150 m² per charge. The two-battery kit lets you mow up to 300 m² by swapping batteries halfway. The bare tool has no battery or charger and only makes sense if you already own LawnMaster MX 24V batteries.
How it navigates and sets up
The OcuMow 16 is a "drop and mow" robot. It uses an HDR camera and what LawnMaster calls Optical Grass Recognition to see where the grass ends, plus ultrasonic sensors to spot obstacles. There's no wire, no docking station and no app. You carry it to the lawn, switch it on, and it mows until the battery is flat; then you take the battery indoors to charge.
That makes it more like a self-driving cordless mower than a typical robot. It saves the effort of pushing a mower, but it won't mow on a schedule while you're out. Our robot vs cordless guide explains when that trade-off makes sense.
It needs clear lawn edges: paving, gravel, or a raised edge of at least 6 cm. LawnMaster rates it for 150–300 m² depending on the number of batteries, and slopes up to 35%.
Cutting
The cut is 160 mm wide, using three pivoting blades on a disc. Height has five positions from 20 mm to 60 mm. There's no edge cutting, and LawnMaster says you'll need a trimmer. The manual lists a guaranteed sound power of 68 dB(A), which is high for a robot mower, so you'll hear it while it works.
App, connectivity and security
There's no app, no wireless connection and no theft tracking. Because you carry it in after each session, theft risk is lower than for a mower left out all week. It has no rain sensor, so don't start it on a wet lawn. As with any mower, check for hedgehogs and other wildlife before you set it going; see our hedgehog guide.
Running costs, warranty and support
The 86.4 Wh MX 24V battery also fits LawnMaster's other MX 24V tools. LawnMaster's UK distributor, Cleva, gives a limited guarantee of 2 years. Prices start from £229.99.

OcuMow 16 questions and answers
Can I run the LawnMaster OcuMow 16 on a wet lawn?
It's best not to. The LawnMaster OcuMow 16 has no rain sensor, so it won't stop by itself if a shower starts, and it relies on you choosing when to run it. Its body is rated IPX4, which covers splashes rather than prolonged heavy rain.
Wet grass causes other problems too. Clippings clump under the cutting disc, the wheels grip less well, especially on slopes near its 35% rating, and a camera-guided mower can find it harder to read the lawn edge when surfaces are shiny with water.
Because it has no dock and you carry it out for each session, the fix is simple: wait until the grass has dried, and bring the mower back in afterwards rather than leaving it on the lawn.
Does the LawnMaster OcuMow 16 go back to a charging station by itself?
No. The LawnMaster OcuMow 16 has no docking station at all. LawnMaster sells it as a "drop and mow" robot: you carry it onto the lawn, switch it on, and it mows on its own until the battery runs flat. Then you take the battery out and charge it on the supplied charger, which LawnMaster says takes about an hour.
That makes it closer to a self-driving cordless mower than a typical robot. You don't have to push it, but you do have to be there to start each session, so it can't keep the lawn trimmed on a schedule while you're away. LawnMaster quotes up to four hours' mowing per 4.0 Ah battery, and rates it for 150–300 m² depending on whether you buy one battery or two. The two-battery kit gives you a second run after a manual swap, not a longer run by itself.
There are advantages to having no dock. Nothing needs installing, there's no wire or app, and because you bring it in after use it isn't sitting in the garden for a thief. It also shares its MX 24V battery with LawnMaster's other tools.
If you want a mower that goes out and returns on its own, look at the LawnMaster OcuMow AMB16 or LawnMaster OcuMow 18, which both have auto-charging docks. Our robot vs cordless guide explains the trade-off.
More questions
Frequently asked questions
Does the OcuMow 16 go back to a charging station?
No. It has no dock. You place it on the lawn, it mows until the battery runs down, and you then charge the battery on the supplied charger, which LawnMaster says takes about an hour.
Does the OcuMow 16 need an app?
No. It has no app, Wi-Fi or Bluetooth, and is operated with controls on the mower.
Will it mow up to my flower beds?
Only where the edge is clear. It recognises grass with a camera, so it needs a hard surface or a raised edge to see where the lawn stops. LawnMaster says you'll need a trimmer for the edges.
